rlhis invention relates to an electric iron switch, and has special reference to elect-ric sad irons adapted to be placed 'in circuit with an ordinary electric light circuit, such irons including one or more resistance coils by which the ironing surface of the iron isheated tor ironing purposes.

@ne oit the objects of my inventiongis .to furnish a switch attachment that may be easily and quickly installed on various types oit irons new in use, without any material modification or change, and without intertering with the usual manipulation ot Jche iron by the user.

Another object ot this invention is uto iurnish the itorwardend of an iron with a switch for controlling the current to the iron, the switch `being' constantly open and located contiguous to the iron handle so that the user oit the iron may so retain a thumb or finger on the switch to hold it close during the use of the iron. l/Vth the switch otherwise open there is a saving in the expense of electric current, and the danger of tire and burning oi' goods is reduced to a minimum.

A further object of this invention is to furnish a constantly open electric iron switch with means for holding the switch closed so that the iron may be heated, preparatory to use, without the constant tension of the user. T his same switch controlling means permits oit the switch being locked isan open position so that it cannot be tampered with by those unifamiliar with the use of the switch.

still further object ofthisinvention is to provide a novel plug adapter or connector which will permit oit the'iron attachment being readily used in connection withan ordinary iron.

I attain the above and other objects by av simple, durable and inexpensive construction that will be hereinafter specifically described and then claimed,.and reference will now be had to the drawings, wherein Figure 1 is a side elevation ot an iron provided with a switch, showing part of the switch removed;

Fig. 2 is a plan of the iron with the handle thereof in horizontal section and the plug removed;

Fig. 8 is an enlarged vertical sectional vie-w oit the electric iron, posts or jacksshowingl my adapter or connector;

Fig. l is a perspective view of an outer member of the connector;

Fig. 5 is a similar View of an intermediate part of the connector; i

Fig. 6 is a perspective view of an inner member ol the connector;

Fig. 7 is a cross sectional view of the iron handle showing' Va switch partly in section, and

-Fig. 8 is a perspective view of a modified form of bracket.

In the drawings, the reference numeral 1 denotes a conventional form of electric iron having the rear end thereofA provided with jacks or posts I2 and 8 which are ordinarily connected to the :heating elements or units within the iron. On top of the iron are bosses 4 provided with screw bolts 5 and 6 for holding the yoke 7 ot the handle 8, said handle being attached to the yoke by screw bolts 9 a-nd 19.

11 denotes a longitudinally disposed bracket arranged parallel to the yokei7, at one side thereof, said bracket having a slotted side extension 12 extending under the head or' the screw bolt 6 to be held thereby, as best shown in F ig. V2. At the forward end ythe bracket 11V is an upstanding .end portion 13 provided with a rearwardly extending angle lug 14; which protrudes into the forward end of the handle 8 and is sandwiched between said handle and the forward end of the yoke 7 to beheld by the screw bolt 9. Since lthe yscrew bolts 6 and 9 form part of an ordinary iron the bracket 11 can be easily and quickly installed. i

15 and 16 denote sections of a switch block preferably made of an insulation material, said sections being connected together by screws 17 and the switch block mounted on the :torwardend of the bracket 11, against the upstanding end 13 thereof, and connected to the angle lug le'by a screw 18. The confronting faces of the block sections 15 and 16 have recesses 19 and 20. Slidable. in the recesses 19 is a push button 21 having a plunger 22 provided with a collar 23 and a head 24, said collar and head being within the recesses 20. Encircling the plunger 22 in the recesses 19 is a coiled expansion spring 25 holding the pushbutton 21 normally elep vated with the collar 23 of the plunger limiting the upward movement .of the pushbutton, but not interfering with depression of the push button by a thumb or finger of the hand on the handle 8.

26 denotes binding posts in the recessesV 2O and attached to one of the block sections,

said binding posts having opposed resilient Contact members 27 adapted to be engaged by the head 24 of the plunger 22 when the push button 2l is depressed. The binding posts 26 have leading out wires 28 extending through a conduit 29 suitably mounted on the bracket 11, said conduit having its Vforward end extending into the switch block. y Y c 30 denotes a double socket or plug detachably mounted o n the posts 2 and 3 of the'iron and said plug has the usual cable 31 for leading in wires or conductors adapted toconduct' an electric current into. the iron. The plug also has sockets 32 and33 with the latter .Y slightly larger than the former in order that a connector can be interposed between the socket .33. and the post 3, said connector permitting of the switch wires 28 being tapped in to one side of the electric circuitof the iron.

34V denotesan. outer member; 35 an intermediatelmember, Vand 36 an inner member, said membersfbeing made of insulation material and connected together by nut equipped screws 37 with some of said screws i holding the connector on the rear downwardly inclined end 38 of the bracket 11.

On one end of the member 34 is fixed a thimble 39 of insulation material andfitted over this thimble is a metallic thimble 40 v adapted to snugly'fit in the socket 33. The

thimbles 39 and 40 have flanged endsconnected to the member 34 by rivets 41 and one of said rivets is employed to hold a connecting strip 42 on the inner face of (the member 134, said connecting strip being also held by a binding post 43 attached to the member 34 and to which binding post one of the switchv leading out wires 28` is connected.

44 denotes a plurality ofyieldfable fingers mounted on the. member 36 and corresponding to an open-thimble to receive. the ,post

3. The fingers V44 are held place by rivets 45 and one of said rivets assistsin-.holding a connecting strip 46 on the member 36 so that a binding post 47 mounted inthe members 34 and 35 may beelectricallyconnected,l

with the fingers 44. .Theother switch leading out wire 28 is adapted to be connected to the binding post 47. VThe lingers 44 eX- Vtend into the thimble 39 and through open-` ings .provided therefor in the Amembers 34 and 35; the member 36 having an opening 48 which permits of the connector being placed down over the post-3,y as shown in lligx.-` A),

49 denotes a. set screw carried by the switchblock section 16 and said Iset screw has its inner end provided witha pin 50 Y Y adapted to engage eitherunder the 'push but-H ton 21 Vor in an annular groovedl of the plrishbutton.V When engaging 'under :thel

push button the switch is held in an open position and thepush button cannot be depressed. By depressing the push button 21 randl screwing inwardly on the set screw 49 the pin 50 will engage in the groove 51 and hold the switch closed7 thus completing a circuit which causes the iron to be heated, The user can so set the switch providing the Y ironjis'on a suitable rest and after the iron switch closed by the thumb of the hand engaging the handle 8, andin this manner the electric iron may be maintained at a desired temperature.V 4

' Since there may be various types of electric irons differing somewhat as to the location of the screw bolts 5 and 6, I may provide another form of bracket 52 and provide said bracket with an adjustable side extension 53 in lieu of the fixed side extension 12 ofthe bracket 11.

l From the foregoing itwill be noted that the iron-attachment includes the longitudinally disposed bracket with the switch at the forward end thereof and the connector at therear end with the connector disposed so thatit Vmay be fitted down over one of the usual posts of an .electric iron, and ywhen the attachment is properlyinstalledthe user of the ironcan readily control the electric current iby the switch at the forward end of the arm, without leaving the iron and operating any other switches.

While in the `drawings there are illustrated the preferred embodiments of my invention, it is to be understood that the structural elements Vare susceptible to such changesin size, shape. and manner of assembling, as fall'within the scopeof the appended claim.

What Il claim is `A opposed block sections secured together and having the confronting faces of said sections cut away to provide outer and inner communicating recesses with'the outer recess cylindrical to afford guide walls and the inner recess` substantially rectangular, a spring distended circumferentially grooved plunger slidableV in the outer cylindrical guide recess andextending into the inner rectangular recess, contact members in the inner recess adapted to be engaged by said plunger7 and a setl screw in one of said block sections extending at a right angle to said plungerand' adapted to secure said plunger in j. 'engagement `with .said contact members. y Y ,l

, In testimony whereof I affix my signature.
